9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Details

'remap_pfn_range' here may map out of size kernel memory (for example, may map the kernel area), and because the 'vma->vm_page_prot' can also be controlled by userspace, so userspace may map the kernel area to be writable, which is easy to be exploitedProduct: AndroidVersions: Android SoCAndroid ID: A-233972091
